We would need to show how semweb solutions are a better solution, or how it is tied too much to healthcare, leaving out life sciences, population science, chemistry, etc. We don't yet have *a* solution for this, we have several. :-) "
Besides the fact that HL7 et al. are already better established in the current healthcare IT infrastructure than RDF/OWL, it does not seem too hard to come up with reasonable arguments in favour of RDF/OWL. I also read other seemingly RDF-friendly pieces of text in that document:
"As mentioned, ONC's CDA is a foundational step in the right direction. However, the thrust of CDA seems
largely that it be an extensible wrapper that can hold a variety of structured reports or documents, each
with vocabulary Â­controlled metadata. While this shares many features with the universal exchange
language that we envisage, it lacks many others. In particular, it perpetuates the recordÂ­ centric notion
that data elements should "live" inside documents (albeit metadata tagged). We think that a universal
exchange language must facilitate the exchange of metadata tagged elements at a more atomic and
disaggregated level, so that their varied assembly into documents or reports can itself be a robust,
entrepreneurial marketplace of applications. In a similar vein, we view the semantics of metadata tags
as an arena in which new players can participate (by "publishing"), not as one limited to a vocabulary
controlled by the government"
